TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOSEPH L. ROUTZAHN, of Frederick City,- Frederickcounty, State of vh'flaryland, have invented new and useful Improvementsin Shutter Fasteners; and I do. hereby declare the following to be anexact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, making a partof this specification, in which- Figure 1 represents the fastener openwide.

Figure 2, half open.

The nature of my invention consists in a semicircular notched iron barpermanently riveted to the inside of one wing of the hinge, the notchesofthe bar falling into the notch ofthe other wing ofthe hinge.

A represents the winged hinge, with notches B and O at the top of thewings. The fastener is a semicircular notched iron bar, D, with squarenotches, E E, on the under side. Theloneencl of this bar D is rivetedpermanently on the inside of one wing, (as at 'G,) but the ber. playsloosely on the rivet H as ar pivot, so that the bar can be raisedor'lowered suciently high to fall into the notches B and C of the wings.The notches of the wings and of the bar are all square-shaped.` Thehinge is fastened by screws to a shutter-blind on the edge of theshutter, as winged hinges are usually screwed on, and when the shuttersare to be bowed the bar rests with its notch E in the notch C,at anyangle required, and'when the shutter isA thrown clear back, the end ofthe bar D rests against the opposite wing, (as seen at J,) and thus theshutterv is held rmly when partly or entirely open.

What I claim as my invention, and desire to secure by Letters Patent,isv The construction of the hinge with its square notches at the top,audits semicircular bar with corresponding notches, when combined andoperated as herein described and for the purposes set forth.
